The lithium battery pack consists of three parts: the battery cell, the protection plate and the casing.
The cells are composed of lithium battery cabinets, and the protection plate is to protect the charge and discharge of the series Li-ion battery packs; When fully charged, it can ensure that the voltage difference between the individual cells is less than the set value (generally ± 20mV), so as to realize the uniform charging of each individual cell of the battery cabinets, which effectively improves the charging effect under the series charging method. At the same time, it detects the overvoltage, undervoltage, overcurrent, short circuit and overtemperature states of each individual cell in the battery pack to protect and prolong the service life of the battery; Undervoltage protection prevents the battery from being damaged due to overdischarge when discharging and using.
